3.2.5 Overtemperature trips and intelligent fan control
The MotiFlex
e
100 contains internal temperature sensors that will cause it to trip and disable if
the control card or output power module temperatures exceed preset values. These values are
listed in the following table, and can also be read using the
TEMPERATURELIMITFATAL
keyword - see the Mint help file for details.

The MotiFlex
e
100 can detect problems with its cooling fan, such as disconnection (fan loss) or
overcurrent caused by stalling. The 10.5 A and 16 A models incorporate two cooling fans; one
fan operates continuously, but to increase overall lifetime and efficiency the second fan operates
only when necessary. Also, if a fault is detected on the first fan, the other one will turn on. The
48 A and 65 A models incorporate four cooling fans; none of the fans are required in normal
conditions, but all four will operate when necessary.
3.2.5.1 Effects of mounting surface and proximity
If the MotiFlex
e
100 is mounted above or below another MotiFlex
e
100 (or other obstruction),
there should be a minimum space of 90 mm to maintain effective cooling. Remember that when
a MotiFlex
e
100 is mounted above another MotiFlex
e
100 or heat source, it will be receiving air
that has been already heated by the device(s) below it.
